Water Impact Simulation of Spacecraft Capsule and the Analysis of Its Factors Influence
As the last step of manned space activity, the return process of spacecraft is the final mark of the success of the mission. There will be a great impact force in the process of water landing, which will do harm to the cabin, the crew and related equipment. So the study on the water impact [...]
The Numerical Methods Research of Coupled Vibration and Sound Radiation of Underwater Structures
The vibration and sound radiation problem of a submarine is in fact a fluid-solid coupling problem. An excited underwater structure will vibrate and produce acoustic field in fluid, and the acoustic field reacts on the structure simultaneously. There is strong coupling between the structure’s surface and water. Therefore, research on fluid-solid coupling is of engineering [...]
